MACHENE FOR CUTTING`THE FRONT-SO-F BOOKS.

Specification forming part of yLettersA Patent No. 59,229, dated October 30, 1866; antedatcd October 20, 1866.

To all whom it may concern:

Be it known that I, ISAAC JONES, of Oamden, New Jersey, have invented an Improved Machine for Cutting the Fronts of Books; and I do hereby declare the following` to be a full, clear, and exactI description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in devices fully described hereinafter, whereby the front edge of a book may be quickly cut to the curved form required, and, whereby the book may be nicely adjusted before being cut, firmly held during the cutting operation, and quickly detached when finished.l

In order to enable others skilled in 'the art to make and use my invention, I will now proceed to describe its construction and operation.l

On reference to the accompanying drawings, which form a part of this specification, Figure 1 is a sectional elevation of my improved machine for cutting the fronts of books Fig. 2, a sectional elevation on the line l 2, Fig. 1, and Fig. 3, a plan view.

A and A are the side fra-mes of the machine, which are connected together by cross-pieces B, B, B2, and B.

On guides a a secured to the'opposite inner sides of the side frames slides aframe, G, and

to each side of the frame is secured one of the arms of an inverted yoke, D, against which bears the upper end of a set-screw, E, turningv in a bracket, I, secured to the side frames.

In the opposite sides of the frame O turn screws F F', each of which extend through a slot in the side frame, and is provided at its outer end with a hand-wheel, Gr. The inner end of each of the said screws turns in a hollow projection, I), 0n a plate, H, which slides freely in the frame G, a collar, i, on the end of the screw preventing the same from being withdrawn from the said plate.

In one end of the frame G slides a vertical rack, K, to the teeth of which are adapted those of a pinion, c, on a shaft, L, the latter passing through a slot in the side frame A and turning in bearings e e at the end of the frame C.

- To the inner side of the rack K is secured a strip, d, of soft metal or wood, for a purpose described hereinafter. t

A screwed rod, M, attached to one end of the frame C, projects through a slot in the cross-piece Bl, and is provided at its outer end with a nut, O, which bears against the side of the cross-piece.

In guide-blocks N N secured to the frame of the machine slides a bar, l?, at the under side of which is a rack, m, and to the latter are adapted the teeth of a cog-wheel, a, on a shaft, Q, which turns in the side frames.

To the teeth of the cog-wheel a are adapted those of a pinion, o, which is secured to a shaft, It, turning in the side frames, and to one end ot' the said shaft It is secured acrank-handle, S.

To a projection, t, at the inner end of the rod P is secured a curved knife or gouge, T.

The book, the front of which is to be cut, is placed between the plates H H with one end resting against the strip a., and the screws F F are turned until the plates are brought firmly against the sides of the book, and the latter occupies a position exactly in the center of the frame C. The frame G is then adjusted vertically by turning the screw E, and is secured after adjustment by means of the nut O, which is turned so as to bring the side of the frame vagainst the cross-piece Bl.

A rotary motion in the direction of its arrow is then imparted to the shaft It, so as to move forward the shaft l? and bring the gouge T against the edge of the book, the gouge being carried across the front of the book until it is embedded in the soft-metal or wood strip d, the front of the book being thus cut to a curved form corresponding to that of the gouge. rlhe bar P is then moved back, the screws F F' are turned so as to draw back the plates H H, the book is removed, and another is inserted in its place, and its front cut in a similar manner.

Bythe use of a machine of this description the front of the book may be quickly' and correctly cut to the form desired, while the book may be speedily and nicely adjusted, and is held firmly in its place during the entire operation.

By the use of the soft-metal or wood strip d the extreme corners of the leaves are held firmly while the knife passes from contact with the same, so that there are no ragged edges.

3. The adjustable frame C, with its adjustable plates H H', in combination with the traversing bar P and its knife T, substantially as and for the purpose set forth.

In testimony wh ereot' I. have signed my name to this specification in the presence of two subscribing Witnesses.

ISAAC JoNEs.
